Amplidata will become part of Western Digital’s HGST subsidiary. The deal is expected to close this month. Western Digital did not disclose the acquisition price.

Amplidata claims its Himalaya object storage software can handle zettabytes of data and trillions of stored objects under a single global namespace. The software was called AmpliStore until Amplidata re-branded it as Himalaya in June 2014.

Western Digital invested $10 million in Amplidata last year, and Amplidata was a joint development partner in HGST’s Active Archive platform. HGST sees Active Archives as large repositories of recently created data that needs to be accessed at least occasionally, unlike cold archived data that is rarely accessed.

Amplidata also has an OEM deal with storage systems vendor Quantum, which uses Amplidata in its Lattus and StorNext archiving products. It appears that relationship will continue, as Western Digital’s press release today quoted Quantum CEO Jon Gacek saying he was “excited about the acquisition” and is looking forward to new partnership opportunities.

Until today, HGST has concentrated more on storage performance products than archiving with its acquisitions. It bought all-solid state drive array vendor Skyera in December 2014, after picking up NAND controller vendor sTec, PCIe-based flash card vendor Virident Systems and application acceleration vendor VeloBit.
